Title: Works great!
Review: We moved from FL to NV and the humidity change really affected us as well as just being in a dusty environment. We put this in our master bedroom and it does a great job to clean the air and add humidity which has made it much easier to sleep. It meets our needs. For reference, bedroom is roughly 20' x 18' with 16' ceilings and a joining 20' x 8' sitting / media room.

Title: Ticking sound actually helps me, and air is clean!
Review: I've used it for a little over a year now, and it's fantastic. I had to move in middle of the pandemic due to the rising cost of rent. But with rising demand in apartments, we didn't have much choice aka carpeted floor. Dad suggested me this, and you can tell it works cuz whenever there's a power outage and i forget to power it back on for a few days, I'll be sneezing haha.Just remember to vacuum or wash the rear filter cover. I forgot to, and dust was caked on - which explained why it felt like it wasn't working properly at one point.The picture is when we were cooking bacon and it smoked lol. It immediately knew there's something's up. (Orange color) So when the light changes color, there's a quiet ticking sound. Honestly it doesn't bother me. In fact, I'd rather it make noise since it let's me know something's in the air. I don't have a great sense of smell, so I can't tell if something's burning. But this does! I know that's not it's intended purpose but it helped me a couple of times. That said, it's soooo quiet. If I have anything going on in the background, I won't hear it.I don't use the humidifier part, but the humidity sensor is helpful!

Title: Does the job. Very quiet.
Review: I think this air purifier/humidifier is worth the money. You can barely hear it running. The air is so much cleaner. I've noticed my husband and one of our house pets has stop sneezing. Very simple easy to use controls (that I love) easy to fill water reservoir. We have two lap dogs and a cat in the house and its so hard to keep the pet hair swept up. The hair was always blowing around but with the humidity being higher its easier to sweep and keep house cleaner. Love it.

Title: Great device but a little noisy
Review: This a high quality humidifier and works great. The only downside is that it makes a loud gurgling noise when it periodically draws more water. The rest of the time, it’s quiet. Because the gurgling noise is periodic and loud, it wakes me up if I run the humidifier during the night, which is what I needed it for. Unfortunately, I have to return it.

Title: Great unit - watch the prices.
Review: Greatly improves air quality.Purchased via Amazon Prime two months ago, new, for 299. Prices fluctuate a lot on these, and other vendors charge even more.In a dry climate, on high fan speed (I have it in a larger bedroom and as such it really only works on high) you have to refill the H2O tank twice a day.It's worth the hassle.Over the years I've tried Winix, Honeywell, Friedrich, Austin Air, Holmes, and others too cheap to mention. This Sharp has worked the best of the bunch. Not a miracle worker, but does what it says it will.Vastly superior to Winix, no contest.Filters - expensive & not available everywhere. Wish the unit came with at least one extra charcoal filter. 3-5 year filter life seems impossible, could happen if your air is already pretty clean. I'll be surprised if I get two years out of this filter set.Looks great, which is a nice bonus. The color-changing air quality indicator is a very nice feature.The clicking of the Plasmacluster is noticeable on lower fan speeds.The unit is designed & built well. Plastic, but doesn't feel cheap. Recessed handles make it easy to move.Really has improved the quality of sleep in the bedroom.

Title: Great for allergy sufferers
Review: We have used this for years in our bedrooms and it really helps with our allergies. I've got the smaller version for my daughter's room. Make sure to get some good quality citric acid to clean the humidifier filter monthly and this thing will last forever. Good food grade citric acid is available here on Amazon and that's what I use, along with a 5 gallon HD bucket. I use the water tank for this thing to weight down the filters carefully so they stay fully submerged.Its not very loud and creates a light white noise for you that isn't too obtrusive.The filters all last a pretty long time and have different change frequencies outlined in the manual. You can get all of the filters from here on Amazon.My allergies are so bad I have to get weekly allergy shots and this really helps. I was also able to get a letter of medical necessity from my allergist so we could claim this on our medical FSA.

Title: Humidifier gets moldy pretty quick
Review: A few days in use and the humidifier filter started to smell like mold. The tip here is add a lil bleach to the water container to prevent that from happening. The so called "Ion" doesnt do crap to mold.

Title: Best air purifier by far
Review: I have had several air purifiers and most of them work great. This one is the best! It has an excellent auto setting. When someone burns bacon or my son brings by his mouse tank it instantly knows and kicks into high drive for a few minutes. I've had this running for three years in California where we've had massive fires and the air in my house is always clean. I like that it tells you if the air is clean or dirty with different colors and it's helpful to see what the humidity is in the house. The only big drawback is that the humidifier doesn't work well at all. Don't buy this for the humidifier function, only to clean your air.

Title:
Review: This is is my second unit and is needed to keep humidity at desired levels. The design appears to be exactly the same although my first unit is well over 10 years old. It is built well, works well and worth its relatively high cost if you are thinking you will need its functions for many years. It does have some drawbacks: there are several filters and some (HEPA) are expensive and you have almost no choices in where to get them; there is routine maintenance required (anything with water almost always does) at least every two or three months; and, the water tank needs refilling twice a day (could be bigger). Final thought, I snapped it up when I saw it available and had the money.

Review: I find this product very good for the money. I placed it in the hall between two bedrooms. It circulates the air quite well and humidifies just enough. Very quite, doesn’t disturb our sleep. The water tank is enough for one days use. Would recommend.

Review: We used to own another Sharp’s air purifier and humidifier in Japan. In Canada, the air quality is good but humidity is low. With this equipment, the air humidity will be much better inside the room.

Review: It works great, cleans out dutsy air quickly and efficiently. I would prefer to manage the humidity myself, but the way around it is to turn off "auto" and manually change the fan speed.

Review: Makes really annoying clicking sound. Sharp customer service was extremely unhelpful, saying it's normal. But it only started 4 months after buying it.. i can't use it anymore it drives me nuts.
